I especially enjoyed the metafiction in Ch IV. The spoof of the Da Vinci Code, that totally tongue-in-cheek encounter with the Lady of the Lake, the upside-down Lovecraftian thing, the beautiful Slavic folktale of the two sisters and the wedding… It was just emotionally compelling enough to sweep me along, and just light enough to be fun.

(By the way, The Witcher was chock-full of that sort of thing, and not just Ch IV -- the hard-boiled detective story spoof in Ch II, the drugged-out hippie druids, the other Lovecraftian storyline in the swamp, that whole Great White Hope boxing thing, and so on.)
